Cucumber 3+-UndefinedDataableTypeException:无法将DataTable转换为Map<String,Boolean>

cucumber-jvm java

Stéphane GRILLON · 技术社区 · 5 年前

我的小黄瓜剧本:

Then I update checkboxes and check radio list 'DEMO_HOME-agree' with 'yes':
    |yes|true|
    |no|false|

我的黄瓜代码:

@Then("I update checkboxes and check radio list {string} with {string}:")
public void selectCheckbox(String elementKey, String valueKey, Map<String, Boolean> values) throws TechnicalException, FailureException {
    selectCheckbox(this.demoPage.getPageElementByKey(elementKey), true);
    selectCheckbox(this.demoPage.getPageElementByKey(elementKey), valueKey, values);
    checkRadioList(this.demoPage.getPageElementByKey(elementKey), valueKey);
}

io.cucumber.datatable.UndefinedDataTableTypeException: Can't convert DataTable to Map<java.lang.String, java.lang.Boolean>.
Please register a DataTableType with a TableEntryTransformer or TableCellTransformer for java.lang.Boolean.

在我的DataTableConfigurer中:

public class DataTableConfigurer implements TypeRegistryConfigurer {

    @Override
    public Locale locale() {
        return Locale.ENGLISH;
    }

    @Override
    public void configureTypeRegistry(TypeRegistry registry) {
        registry.defineDataTableType(new DataTableType(Map.class, new TableEntryTransformer<Map>() {
            @Override
            public Map<String, Boolean> transform(Map<String, String> entries) {
                Map<String, Boolean> newMap = new HashMap<>();
                entries.forEach((k, v) -> newMap.put(k, Boolean.parseBoolean(v)));
                return newMap;
            }
        }));
    }

}

您已经注册了 TableEntryTransformer 通用的 Map 输入而不是 Map<String, Boolean> 我怀疑你打算这么做。

但是,错误消息会询问您是否愿意

请使用TableEntryTransformer或TableCellTransformer for java.lang.Boolean注册DataTableType。

@Override
public void configureTypeRegistry(TypeRegistry typeRegistry) {
    typeRegistry.defineDataTableType(
            new DataTableType(
                    Boolean.class,
                    Boolean::parseBoolean
            ));
}

此外,因为您的表顶部没有标题,但您必须将表转置到侧面。这将使您的桌子变成:

|yes|no|
|true|false|

可以在要素文件中重新定位表格,也可以使用 @cucumber.api.Transpose 对 values 参数:

public void selectCheckbox(String elementKey, String valueKey, @Transpose Map<String, Boolean> values) throws TechnicalException, FailureException {
